1200V DC Photovoltaic Switch for Safe Solar Systems
The 1200V / 32A DC photovoltaic switch is a safety component that allows for controlled isolation of the solar installation from the inverter or electrical panel, without risks to equipment or users. Designed for outdoor mounting in harsh weather conditions, it is the right solution for both residential installations and larger photovoltaic systems. Its IP66 sealed enclosure and compliance with IEC60947-3 and AS60947.3 standards make it a reliable long-term choice.
What you get with this product
- Safely and quickly isolate the solar installation — the 1200V DC switch handles high voltages specific to photovoltaic systems without the risk of electrical arc
- Functions flawlessly outdoors for the entire life of the installation — IP66 protection prevents the ingress of dust and water jets from any direction
- UV-resistant casing does not deteriorate with prolonged sun exposure — treated plastic material maintains rigidity and sealing for years
- Cable connection is simple and secure — the 4 M20 connectors allow for an orderly passage of cables without special tools or improvisations
- You can physically lock the switch in the OFF position with the included padlock — essential for safe intervention by the installer or electrician
- Comply with normative requirements for PV installations — IEC60947-3 and DC-PV2 certifications ensure compliance with European standards for solar systems
How it works and how to install it
The switch is mounted on the path between the solar panels and the inverter, on a flat support — wall, metal structure, or outdoor panel. Connections are made through the 4 M20 cable glands, through which the DC cables from the panels and towards the inverter are inserted, after which the cap is manually tightened for sealing. Switching between ON and OFF is done with a single movement of the rotary handle, and the OFF position can be locked with the included safety padlock, preventing accidental restarting during work.
Frequently Asked Questions
Can I use this switch with any type of solar inverter?
Yes, it is compatible with any inverter that operates on DC current, regardless of the manufacturer, as long as the system voltage does not exceed 1200V and the maximum current does not exceed 32A.
Is it suitable for roof mounting or unprotected outdoor use?
Yes, IP66 protection allows direct outdoor mounting, including on roofs or structures exposed to rain, dust, and UV radiation, without the need for an additional protective box.
What is the compatible cable diameter for M20 connectors?
M20 cable glands are generally compatible with cables having an outer diameter between 6 and 12 mm, covering the usual range of DC cables used in photovoltaic installations.
